电渣重熔GCr-15轴承钢的弯曲疲劳S-N曲线——第二研究室,第一机械工业部轴承研究所研究报告,1964年4月(已出版)本文测定了电渣重熔和空气电炉熔炼GCr-15轴承钢的弯曲疲劳S-N曲线,采用了数理统计的韦布尔(Weibull)分布法处理试验数据,分析对比了两种轴承钢的弯曲疲劳S-N曲线和冶金质量.试验证实:在破坏概率P=0.50时,电渣重熔轴承钢的弯曲疲劳强度比普通钢提高16%左右,并证实了利用韦布尔分布法处理弯曲疲劳试验结果是比较适宜的.
Bending fatigue SN curve of electroslag remelting GCr-15 bearing steel - No.2 Laboratory, Research Institute of Bearing, No. 1 Ministry of Machinery Industry, April 1964 (Published) In this paper, the electroslag remelting and air- Smelting GCr-15 bearing steel bending fatigue SN curve, the use of mathematical statistics Weibull distribution test data processing, analysis and comparison of the two bearing steel bending fatigue SN curve and metallurgical quality.Experiment confirmed: the probability of failure When P = 0.50, the bending fatigue strength of ESR bearing steel is about 16% higher than that of ordinary steel, and it is proved that it is more suitable to use the Weibull distribution method to deal with the bending fatigue test results.
